Some religions can be largely inherited. They are religions you adhere to because of your family background or nationality.
“Of course I’m Lutheran. Im Norwegian.”
“I’m Italian, so I’m Catholic.”
“I’m Hindu because I’m Indian.”
In modernity, however, the emphasis is on individual choice and decision. Young people do not want to follow a path that they have not chosen for themselves. This is why traditional inherited religion-Catholic and mainline Protestantism – is in sharp decline. But evangelical faith is far better suited to such a cultural situation because it insists on a personal decision of faith and a conversion experience for everyone.
